Ricoh aficio 1075 end temparature display

[georgereth]

i have a problem in the sp 1106 (temparature display) shows only the 001 center thermistor and does not show the 002 end thermistor temparature display.
any ideas about that ?
thanks

Sounds like the thermistors or the heaters aren't connected, but that's pretty obvious with a visual check. I've seen the connector on the back of the fuser get oxidized due to breakage, have you looked into that? Let me know.
Good Luck!

Also check for paper in both ends of the connector on the fuser. I've seen paper get stuck inside the connector even after a jam was removed. You also could have an open thermistor, but I'm assuming you've swapped them out at this point in testing.

Try putting some small 1mm spacers behind the screws on the fuser connector between the connector and the fuser frame. The contacts on these machines can wear out and possibly corrode causing bad electrical connection. The spacers will put the contacts at a slightly different location. If a single spacer doesn't work, try 2 1mm spacers. If the spacers don't correct the issue you may have to replace the connector inside the machine.
